I listened to that video again and most of the sentence that was taken from the video I interpreted like this:
with a base plate of pre-famulated amulite: the outlet plate
surmounted by a malleable logarithmic casing: the outlet box
in such a way that the two spurving screws: the screws holding the plate
are in a direct line with the panametric phlam
so fitted to the ambifacient waneshaft: the holes in the box for the screws
that side fumbling is effectively prevented: that keeps the plate from moving
LOL ...
