Abstract
A torque transmission device that includes: a hub rotatable about an axis of rotation, the hub having an orifice delimited by an inner surface bearing axial hub splines distributed circumferentially around the axis of rotation; and a shaft having a shaft end portion delimited by an outer surface bearing shaft splines, the shaft splines cooperating with the hub splines to transmit torque. The shaft end portion is intended to be inserted into the orifice through an open axial end of said orifice. Each hub spline terminates toward the open axial end in a point and two chamfers arranged on either side of the point.
