Abstract

According to an illustrative example of the invention, a flywheel is screwed to a crankshaft by a central bolt. The flywheel and the crankshaft are further provided with radially extending teeth in opposite annular contact faces. These teeth are engaged such as to center the flywheel with respect to the crankshaft and to permit torque transmission between the crankshaft and the flywheel. An angular positioning pin of the flywheel engages into a pin receiving bore of the crankshaft.
