An assembly for swinging an external handle of a tank dome valve on a tank dome about a generally horizontal axis has a gearbox and an air motor. In a preferred embodiment; a housing is cooperatively formed by the gearbox casing and the motor cover: The gearbox contains a worm that meshes with a gear that turns within the casing. The air motor turns the worm; thereby turning the gear. An adapter that is external to the casing has a spline that passes through an aperture in the casing to mesh with an internal spline of the gear. The adapter: is shaped for engagement with the handle of the tank dome valve. The housing and adapter are arranged such that, when the adapter is in engagement with the valve handle and the motor is operated to turn the gear via the worm, the far end of the motor cover is forced to hear against the tank dome and consequently force the adapter to swim the handle.
