A torque calibration apparatus 10 such as a test rig includes a shaft 14 with one end arranged to be driven by a torque tool 12. An angle monitoring device (24, Figure 5) is arranged to detect the degree of rotation of the shaft. A brake 16 is arranged to act on the shaft. A controller (30, Figure 5) is arranged to control the application of the brake based on the detected degree of rotation of the shaft. The brake may be a compressed air brake. A static torque sensor may be arranged to detect the torque applied to the shaft. |
