A torque transmission device, for driving or in drives of agricultural implements or self-propelled working machines, has a coupling (6) with a coupling housing (7) including a connection plate (10) and a coupling hub (8). Torque transmission elements (9) are positioned between the two in at least one rotational direction for transmitting a torque between the two. A driving member (20) defines a longitudinal axis (14). The driving member (20) is provided with distributedly arranged second driving elements (22) around the circumference of and radially projecting from a driving member portion (21). Gaps (23) are formed in a circumferential direction between the second driving elements (22). A support plate (12) is present on which the driving member (20) is rotationally supported around the longitudinal axis (14). First driving elements (15), as distance holders, retain the support plate (12) at an axial distance to the connection plate (10) on the coupling housing ( 7). A space (17) is formed between the driving member ( 20) and the connection plate (10). The driving member portion (21) of the driving member (20) is received in the space (17). The first driving elements (15) engage driving member (22) in the gaps (23) in a circumferential direction around the longitudinal axis (14) with a limited rotational free motion in reference to the connection plate (10).
