Zusammenfassung:	A device is provided for determining a steering torque in a motor vehicle. The device includes a first shaft a second shaft, a twistable means of connection, a stator means, a multi-pole magnetic means, and a first sensor means and a second sensor means. The first shaft is connected to the second shaft via the twistable means of connection, and the magnetic means is fixed to the first shaft. The stator means is fixed to the second shaft, and the first sensor means is designed for measuring, in the case of a relative rotary movement of the magnetic means relative to the stator means, a first magnetic flux density in a first direction. The second sensor means is designed for measuring, in the case of the relative rotary movement of the magnetic means relative to the stator means, a second magnetic flux density in a second direction. The second direction is opposite to the first direction, and the second sensor means is arranged to be rotationally offset by more than 90° relative to the first sensor means.
