Abstract
A plug plugs into a ROV drive bucket limiting rotation of a drive shaft therein to say 15° and reducing the build-up of marine growth in the bucket. As shown it includes a polyethylene body (which may be made in two parts 12, 13) housing a metal socket 11 mounted for limited angular orientation therein. The socket has a twenty four point aperture or recess (22) which fits over a squared end of a drive shaft 10 at various angles orientation. The socket has external splines (20) which fit loosely in wide internal grooves (21) in the body and self-orientates within the body when the body is plugged into the bucket. The plug has a pair of diametrically opposite dogs (4) which engage in slots (5), included in flanges on conventional buckets.
