Zusammenfassung:The present invention relates to a motor vehicle rotary electric machine (100) drive assembly, the drive assembly comprising a rotor shaft (2) extending along a longitudinal axis (X) and a connecting piece (4) providing connection between the shaft and the torque transmission system comprising a bore (41) for the passage of the rotor shaft, the drive assembly being characterized in that the bore comprises a first wall (41a) extending axially and a cylindrical second wall (41b) extending axially in alignment with the first wall, and in that the rotor shaft comprises: -a first surface (21) extending axially and cooperating with the first wall of the bore to centre the connecting piece around the rotor shaft; and-a second cylindrical surface (22) extending axially and provided with knurling, with a diameter (A) greater than the diameter (A′) of the second wall of the bore, the connecting piece being force-fitted onto the rotor shaft by means of the knurling.
