A torque measurement device including: a power shaft transmitting rotary torque about the axis of the power shaft; a first wheel carrying angle marks, the wheel being secured to the power shaft; a reference shaft including a second wheel carrying angle marks; and a sensor placed facing at least one of the wheels to determine the torque transmitted by the power shaft. The first wheel includes first and second series of angle marks and the second wheel includes third and fourth series of angle marks. The marks of the first and third series are mutually parallel, while the marks of the second and fourth series are mutually parallel and are inclined relative to a first axial plane containing the axis, the marks of the first series being inclined relative to the marks of the second series, whereby the signal supplied by the sensor is representative of temperature of the power shaft. |
