The housing is rotatably journaled relative to the drive shaft via bearings. The drive disk has a profiling to increase the transmittable torque and rotates in a working chamber formed in a space formed inside the housing. The housing has a supply chamber communicating with the working chamber via a bidirectional duct(s). Working fluid is introduced and drained to and from the working chamber solely through the bidirectional duct(s). Working fluid is introduced and drained from the working chamber substantially from the outer radial region of the working chamber.
