The present invention relates to transferring torque between a first unit, which is typically a mobile machine or a robot, and a second unit, which is typically a fixed or stationary machine. The units are arranged such that a drive coupler of the first unit designed for delivering torque about a drive axis can engage the driven coupler, which belongs to the second unit and has a driven axis, along an engagement direction that is nearly perpendicular to the direction of the driven axis. A lateral displacement mechanism in provided is in the first unit to achieve a first-order coaxial alignment between the drive and driven axes. Additional measures such as compliance mechanisms are provided for improving engagement, coupling and reducing the level of axial misalignment in the apparatus and methods of the invention.

The invention relates to a valve unit, comprising a housing (1), a flap (2), which is rotatably arranged in the housing (1) and which is connected to a flap shaft (3) supported in the housing (1), an electric motor (4) for driving the flap shaft (3), and a transmission (5), which is arranged between the electric motor (4) and the flap shaft (3). A coupling (7), which consists of a flap-side component (10), an intermediate piece (9), and a transmission-side component (8) is arranged between the flap shaft (3) and a shaft (11) of the transmission (5). At least one of the three coupling parts (8, 9, 10) has at least two first holes (12) of the same radial orientation. Furthermore, at least two second holes (13) are arranged, which are oriented perpendicular to the first holes (12). Molded elements (14, 15) of an adjacent component (8, 9, 10) of the coupling (7) engage in the holes (12, 13) and the holes (12, 13) have a greater extension with respect to the radial orientation of the holes than the molded elements (14, 15) that engage in the holes.

The invention relates to a torque transmission device including a driving member intended to rotate a driven member by means of an intermediate element (11) comprising at least two substantially perpendicular grooves (12, 13) in which studs of the driving member and of the driven member are inserted and guided. Each groove (12, 13) has two opposite guide faces (14, 15), including a first face (15) equipped with at least one cylinder (19) which has an axis parallel to the axis of rotation of the device and which is intended to limit the friction of the corresponding stud. In addition, at least one resilient flange (21) is attached to the intermediate element (11) in order elastically to hold the cylinders (19) in the grooves (12, 13) in the axial direction.

Le dispositif (8) réalise un accouplement entre l'arbre (7) du moteur électrique d'assistance (2) et une vis sans fin (4) constituant l'arbre d'entrée du réducteur (3). Deux flasques (9, 10), comportant chacun deux têtes sphériques (12, 15) diamétralement opposées, sont montés l'un en regard de l'autre, respectivement sur l'arbre (7) du moteur électrique et sur l'extrémité (17) de la vis sans fin. Entre les deux flasques est insérée une pièce d'accouplement (11) en forme de disque, comportant sur chacune de ses faces deux rainures (18, 20) à fond sphérique, diamétralement opposées, logeant les têtes sphériques des deux flasques, les rainures (18) d'une face étant disposées suivant un diamètre perpendiculaire aux rainures (20) de l'autre face.
