Claim Text:
1. A coupling and control assembly including a sensor for providing an electrical signal for electronic transmission control, the assembly comprising: a controllable coupling assembly including first and second coupling members supported for rotation relative to one another about a rotational axis, the first coupling member having a first coupling face oriented to face radially with respect to the axis and having a locking element and a sensor, the second coupling member having a second coupling face oriented to face radially with respect to the axis and having a set of ferromagnetic or magnetic locking formations, the first and second members being positioned relative to each other so that the locking element and the sensor are in close-spaced opposition to the locking formations; and an electromechanical component including a reciprocating member, the component being supported so that the reciprocating member moves the locking element across a gap between the coupling faces in response to the component receiving an electrical control signal, the locking element abuttingly engaging one of the locking formations in a coupling position of the locking element to prevent relative rotation in one direction about the axis, the sensor sensing magnetic flux to produce an electrical output signal indicative of a speed of the relative rotation wherein a variable magnetic field is generated in response to rotation of the locking formations past the sensor.
