Classification: CPC B  G | IPC B  G

Claim 0:
1. A force application device for a control stick of an aircraft, wherein the control stick comprises a control lever connected to at least one motor comprising a drive shaft, the drive shaft being rotationally movable about an axis, the force application device comprising:
a first pin connected to the drive shaft,
a casing configured to be fixed with respect to the aircraft,
an electromagnet,
an actuator that is movable with respect to the casing, said actuator comprising a magnetic material,
a coupling device comprising an input mesh, connected to the casing, and an output mesh configured to cooperate with the input mesh, said output mesh comprising a second pin,
a first tooth and a second tooth configured to clamp the first pin and the second pin,
wherein the force application device has an operational configuration where the electromagnet is active and the output mesh is distant from the input mesh such that the second pin is rotationally mobile about the axis, and a locking configuration where the electromagnet is inactive and the output mesh is meshed with the input mesh such as to rotationally lock the second pin with respect to the casing.
