Abstract
A hollow tubular structure of a distributor rotor driveshaft having a relatively high coefficient of thermal expansion is mated with an axially aligned metal driving member having a relatively low coefficient of thermal expansion. The tubular structure contains an internal socket configuration which conforms with and surrounds the external surface of the metal driving member. Rotational driving forces are communicated from the metal member to the tubular structure throughout a wide range of temperatures due to a compression spring that surrounds a portion of the tubular socket to restrict its expansion.
