The rotary joint (10; 110) further comprises an intermediate member (18; 118) which is hinged (44; 168) at an end thereof to the output member (12; 112) so as to rotate relative to this latter about a second axis of rotation (x 2 ) parallel to the first axis of rotation (x 1 ), abuts at its opposite end against said elastic means (20, 64; 120) and is hinged (46; 150), at an intermediate point thereof, to the input member (16; 116) so as to rotate relative to this latter about a third axis of rotation (x 3 ) parallel to the first axis of rotation (x 1 ), whereby the transmission of the torque between the input member (16; 116) and the output member (12; 112) takes place via the intermediate member (18; 1 18). The second actuator device (22; 122) is arranged to change the position of the hinge point at which the intermediate member (18; 118) is hinged to the input member (16; 116) so as to change the distance between the second axis of rotation (x 2 ) and the third axis of rotation (x 3 ).
