1. An electromagnetic actuating device for a torque transmission system, the electromagnetic actuating device comprising:
a shell arranged around an axis X, the shell being fixed relative to the axis X and comprising walls defining an annular cavity which houses a coil and at least partially a plunger which is able to move axially along the axis X to actuate a coupling device, the actuating device being characterized in that the shell also comprises a recess and the actuating device comprises a detection lug fixed to the plunger and passing through this recess, wherein the detection lug is able to be detected by a sensor so as to generate a signal representative of the axial position of the plunger, wherein the plunger is centred by its outer circumference on the shell.
