Abstract
Device for coupling an inner shaft and an outer shaft which slide along their common axis with balls positioned between the two shafts. The balls rest directly in axial grooves of the outer shaft and on two rails positioned in axial grooves of the inner shaft. The two rails pivot about the balls, by pressing against flanks of mating curved profile of the axial groove, and are held in place by an elastic element which presses against the bottom of the axial groove.
