Abstract: An opening and closing mechanism for a blast resistant pivoted door includes a torque tube assembly connected between a rotary actuator and the door, the torque tube assembly being arranged to absorb the rebound of the door after a blast to help prevent damage both to the actuator and the door by the rebound. Preferably the torque tube assembly is formed by a central shaft arranged inside a tube, one of the ends of the central shaft and tube being fixed together with the other end of the shaft being connected to the rotary actuator and the other end of the tube being connected to the door.
