Abstract
An anti-rotational locking apparatus for locking an elongate rotatable element in a particular rotational position with respect to a housing include: a sleeve having an internal profile for slidably receiving therethrough a rotatable elongate element having a portion with an external profile configured to positively engage with the internal profile of the sleeve; a housing; and a locking pin. The sleeve has a flange with a first opening therein and the housing has a second opening therein, the locking pin being insertable in the openings. The flange is arranged for slidable alignment with the second opening in the housing such that when the openings are aligned, the locking pin may be inserted in the openings to lock the flange to the housing and thereby prevent rotation of the flange and of an elongate element extending therethrough and engaged therewith with respect to the housing.
