Abstract: An apparatus (10) and method for controlling an angular position of a camshaft (12) in an internal combustion engine having a camshaft phaser (14) for controllably varying the phase relationship between a crankshaft of the internal combustion engine and the camshaft (12). The camshaft phaser (14) can be actuated by an electric motor (16) having an actuator shaft (18) operating through a gear reduction drive train (20) having a stationary adjusting member (22) which rotates when a phase change adjustment is desired. A sensor (30) can generate a signal corresponding to an angular position of the stationary adjusting member (22) of the gear reduction drive train (20). An engine control unit (40) can adjust a position of the camshaft (12) through operation of the electric motor (16) for rotating the stationary adjusting member (22) based on the generated signal corresponding to the angular position of the stationary adjusting member (22).

Abstract: A coupling assembly (20, 120, 220) and method can include a first rotatable member (22, 122, 222) and a second rotatable member (26, 126, 226) defining a cylindrical hub portion having a plurality of springs (42, 142, 242) interposed between the cylindrical hub portion of the second rotatable member (26, 126, 226) and the first rotatable member (22, 122, 222) for transferring rotational torque between the first and second rotatable members. A plurality of load-bearing surfaces (32, 132, 232) associated with the first rotatable member (22, 122, 222) are engageable by the plurality of springs (42, 142, 242) to accommodate radial clearances (34, 36, 134, 136, 234) between the first rotatable member (22, 122, 222) and the cylindrical hub portion while providing rotational drive torque from the first rotatable member (22, 122, 222) to the second rotatable member (22, 122, 222) through the plurality of springs (42, 142, 242).
