A camera mount 2 comprising a rotatable connector 21 for connection to a camera. A motor 29 rotates the connector and a torque-limiting device (218, Figs 9 & 10) limits the torque transmittable between the motor and the camera. The torque limiter can act to protect the motor from excessive forces applied to the camera. The motor may be a stepper motor and the mount may comprise electronic circuitry 28 for controlling parameters such as the speed, direction and duration of the rotatable connector, these parameters may also be displayed on a LCD display 23. The torque limiting device may comprise a first component of plastics material which may be in an interference fit with a second component to transmit torque up to a predetermined limit, beyond which the components may slip against each other. |
