An apparatus for transfer of a torque from an internal combustion engine to an auxiliary unit has an auxiliary unit shaft and a pulley rotatably disposed on the auxiliary unit housing. The pulley and the auxiliary unit shaft are connected with one another by an overload protection device configured to interrupt the connection between the pulley and the auxiliary unit shaft if a predetermined torque is exceeded. The overload protection device has a spring washer having multiple spring arms connected, on the end side, with connection elements of a disk-shaped driver until the predetermined torque is reached. Each connection element is configured as a pocket-shaped mounting in the driver, wherein the respective spring arm end lies against a contact surface of the pocket-shaped mounting under spring tension, with force fit. The respective pocket-shaped mounting is configured as a hook-shaped crosspiece cut out of the driver in certain regions.
