摘要

At least one fixed engagement means (27) fixed relative to a first component (10) engages between two adjoining windings of a wound coil or spiral spring (35) rotationally secured relative to the second component . One component is driven in rotation relative to the other. The centre axis of the spring intersects the centre axis of the second component part inside the second part.
