play in supernova insert for NOVA DVR

I dunno about what you have, but the back side of the insert on any chuck should seat firmly against the shoulder on the spindle of the lathe. If it won't thread on far enough to do that, you may have to make or buy a spacer.

The other possibility is that the flat end of the chuck thread insert may not be seating against shoulder on the DVR spindle. (or both.)

Most likely, it is the wrong insert. My guess is that you have ended up with a M33 x 3.5 insert which is the size used on the DVR in Europe (and is also the size for most Oneway lathes). Likely it accidently got mislabled or mispackaged. So it is a DVR insert, but not the 1.25 x 8 used for the US lathes.
