Claim 17:
18. Torque motor having a housing, at least one piston which is accommodated axially displaceably in the housing and which can be driven axially by action of a pressure medium in a pressure chamber of the pressure chambers arranged on either side, and having at least one motor shaft which is mounted in the housing so as to be axially fixed and rotatable about an axis of rotation, said piston being provided with a shaft hole, said shaft hole and said motor shaft being in screw engagement with one another and being guided in a rotationally fixed manner relative to the housing, so that the action of the pressure medium causes the piston to move axially, the axial movement of the piston is converted into a pivoting movement of the motor shaft via the rotationally fixed guidance of the piston in the housing and the screw engagement with the motor shaft, characterized by a device according to claim 1, in which the first part of the torque motor is formed by the housing and the second part of the torque motor is formed by the motor shaft and link plates connected to the motor shaft.
