An electric braking device for measuring the torque of an engine includes a rotor rotating with a shaft and a stator which is tiltably supported in a housing by a bearing at either of its front ends, each end being provided with a disk-shaped bearing shield with a pivot journal. To prevent the measured results from being influenced by the stator bearings hydrostatic swivel bearings are used, one being axially movable and the other axially immovable. Each hydraulic swivel bearing includes a ring slipped over a pivot journal of the bearing shield the ring being supported by two bearing bodies secured against rotating, the latter being located one on either side of a longitudinal center plane containing the shaft axis and below a transverse plane containing the shaft axis and being normal to the center plane. Each bearing body includes a bearing pad and a supporting body permanently attached to the housing, the bearing pad is tiltably supported by the supporting body, and the ring of the axially immovable bearing is supported by the bearing pad so as to be secured against axial shifting.
