HaHa, I was thinking it was a thread on government in America!
The Oneway chucks come with a wormwood screw that is machined with four grooves to line up with the jaws so it can't spin in the chuck and a recessed groove that keeps it from pulling out of the jaws. http://www.oneway.ca/chucks/woodworm.htm As long as those all line up in the Nova jaw setup it should be OK. But if not, it would become a safety concern IMHO.
My Barracuda 2 (CSC3000C) set came with a screwchuck that looks identical to the Oneway you referred to. Probably made by the same manufacturer. (The main chuck body and jaws sure look the same too.)
I like mine. It holds real solid. The four slots and the groove are good features. These should fit most other brand chuck systems OK.
