Abstract
A coupling system including at least two sub-units, one of which is pre-assembled on the engine side of a motor vehicle drive train, namely on the output shaft of the engine, and the other sub-unit is pre-assembled on the transmission side of the drive train. The pre-assembled sub-units each include respective interengaging teeth to provide a positive drive connection, and the teeth are biased toward each other to reduce circumferential play and thereby reduce noise that would be generated during operation of the drive train.
