34. An assembly device with a motor-driven screw device for the tightening or loosening of screws, with a screw head and a housing, wherein the screw device comprises:
-
a first angle-measuring device for the detection of the rotation angle of the housing about the axis of the screw head relative to the surroundings; wherein the assembly device comprises a detection unit for the detection of erroneous sensor data in a rest state, comprising; means for detecting the rest state, and means for comparing sensor data measured in the rest state with one or more predefined threshold values. - View Dependent Claims (35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53)
