Abstract

The present invention generally relates to the attachment of a centrifugal mass or a modular clutch to the output end of a crankshaft of an internal combustion engine. For this purpose, axially-oriented gear teeth can be introduced in both parts, e.g. a serration, and there can be a central screw element which can extend into a threaded portion in the crankshaft. The present invention teaches that an axially-oriented spring bias can be applied to both parts to create a reliable connection between the parts of the gear teeth.
