Patent ID: 7166031

Claim:
A torque transmission device for driving or in drives of agricultural devices or self-propelled working machines, comprising: a coupling having a first coupling element with a connection plate, a second coupling element rotationally arranged to the first coupling element, at least one torque transmission element transmitting a torque in at least one rotational direction around a longitudinal axis between the first coupling element and the second coupling element; first driving elements connected to the connection plate; and a driving member including rotational abutments, said driving member is rotated by hand by the user for aligning a universal joint shaft connected to said driving member and for enabling the rotational abutments to be brought into abutment with the first driving elements for a torque transmission around the longitudinal axis after said driving member passes through a predetermined rotational torque free and bias free motion, and said driving member rotationally supported around the longitudinal axis on the connection plate or on a component connected to the connection plate.
