The invention is related to servomechanisms with internal feedback to control torque. The invention allows expansion of the range of controlled force values. The invention is realized in several ways: by combining different measuring methods of acting forces, combining resilient members with different deformation coefficients in the coupling, using different types of motors in combination. Optionally a force sensor with non-linear dependency is used. Additionally it is possible to change the mode of operation by changing the feedback signal coefficient of the acting force. Areas of application: remote-controlled light machines, robots, manipulators, radio-controlled models, steering parts for cameras, interfaces to interact with living organisms. When invention is used to rotate camera, high rotation speed and high precision of position is maintained.˙
