SUBSTANCE: method comprises determining time intervals between the moments when double-polar pulses of electromotive force of the magnetic pickups passes through zero, on-off time period of the pulses, and their ratio that is proportional to the torque. The device has two axially aligned shafts that are interconnected through a flexible member. Both of the shafts are provided with teeth. The angular shift of the teeth is zero when the torque is absent. Two magnetic shafts are mounted parallel to the axial line of the shaft so that, when any tooth passes through the magnetic field of the corresponding pickup when shafts rotate, the pickup generates double-polar voltage pulse. When the torque exists, the flexible member is deformed, and the angle between the first and second teeth differs from zero. The time interval between the pulses of the first and second pickups is proportional to the twisting angle of the member, i.e. to the torque.
