This invention is a device for real-time measurement of torque output from an automobile engine. The device measures the deformation of damper springs of a planar clutch plate and interprets the deformation as the output torque while the automobile is in operation. The device is comprised of (i) a planar disc clutch plate which includes damper springs, (ii) first and second sets of posts which are welded onto the clutch plate, (iii) a signal pick-up sensor and (iv) an electronic circuit to process the picked-up signals.
