Abstract
A system for rotationally coupling telescopic interior and exterior shafts, which are disposed so that they can slide one within the other along a common axis, includes a first rotational coupling between the two shafts which is constituted by a rotation friction system. A second rotational coupling between the two shafts is constituted by internal and external splines. The internal splines are on the periphery of the end of the interior shaft and the external splines are on the internal face of the exterior tubular shaft so that a normal rotation torque is transmitted by friction and an exceptional rotation torque is additionally transmitted by the splines.
