摘要

Device (1) for transferring torque from a first machine part (2) to a second machine part (3) connected by at least one screw (4) comprises a coupling element (5) that is displaced on tightening the screw so that it engages in a form-locking manner both in a recess (6) in the first machine part and in a recess (7) in the second machine part at least in the peripheral direction (U). Preferred Features: One machine part (2) is part of a two-weight flywheel of a drive train of a motor vehicle. One machine part (3) is part of a rotor of an electric machine. The screw passes through the coupling element.
