# Device for coupling two shafts

## Abstract

A device for coupling two shafts adapted to turn about a common axis includes a rotational coupling system associated with an axial retaining system. The rotational coupling system includes conjugate profiles at the ends of the shafts. The axial retaining system comprises a two-part sleeve coupled axially to the shaft and cooperating with a spring disposed inside the sleeve. The end of each shaft is surrounded by the sleeve. The spring operates after releasing an arming system including studs on the sleeve cooperating with cams at the end of one of the shafts.
