Abstract
A high performance coupling intended to transmit a torque from a motor element to a driven element, each of the two elements having at least two teeth symmetrical in relation to the axis of rotation and having generatrices parallel to this axis, each tooth being constituted by flat surfaces symmetrical in relation to their bisecting plane and being connected by curved surfaces, characterized in that each tooth is provided with at least four flat surfaces, with at least two drive generatrices for a given direction of rotation and with at least two different angles of attack. This new coupling finds its application in the field of screws and nuts, and the corresponding spanners, and also for transmission connections and couplings and the necessary tools.
