A compact torque measuring device for a gas turbine engine which has an output shaft. The torque measurement device includes a pair of tubular concentric shafts of elastic deformable material. The inner shaft is fixed to the output shaft and includes peripheral reference teeth fixed to the output shaft. The concentric shafts are fixed together at the other end in a cantilever manner. Peripheral teeth are mounted to the outer concentric shaft adjacent and interposed with the reference teeth. A magnetic electrical detector is provided to measure relative displacement between the teeth, and thus the torque magnitude can be determined.
