Abstract
A system for coupling an inner shaft and an outer shaft which slide one within the other in the direction of a common axis, the system comprising balls disposed between the inner shaft and the outer shaft in axial grooves on the inner shaft and in axial grooves on the outer shaft. Thrust is applied to each row of balls by an axial coil spring which bears in the groove and which applies thrust to two races of the balls which come into contact with the groove.
