A camera support apparatus for supporting a video camera comprises a drive train device (1), a first inductive position sensor (23), (14) attached to a rotational output device (11) of the drive train device (10), and a second inductive position sensor (2), (3) attached to a rotational input device (4) which is operably connected to the drive train device (1), whereby the inductance sensed by the first position sensor (23), (14) is indicative of the rotational displacement of the rotational output device (11) and the inductance sensed by the second position sensor (2), (3) is indicative of the rotational displacement of the rotational input device (4).
