A coupling for joining two co-axial shafts, for both rotation and in the axial direction, comprising a male part integral with one of said shafts, a set of teeth for rotatably driving on said male part, a female part on the other of said shafts, a conjugate set of teeth on said female part, said one part being engaged in said other part with a certain amount of radial play which allows the axis of the set of teeth of the male part the function of pivoting slightly with respect to the axis of the set of teeth of the female part, and means for axial interconnection of the two shafts, said means comprising a ball carried by the end of said one shaft adjacent said male part, two cups axially connected to said other shaft, and having conjugate surfaces between in which said ball is closely held, means mounting said cups in such a manner that said cups are slightly displaceable in the radial direction relative to said other shaft, the two sets of teeth having profiles which permit the axes of the two shafts to pivot slightly relative to one another about a point which is at the center of the sets of teeth and which also permits the two shafts to transmit torque under the right conditions.
