Almost lost a wheel

I read the info banzaibullit submitted from Maximum Motorsports. It does seel to describe spacers which use the same lug studs as the wheel. My adapters bolt to the existing drum/axle and have five additional lugs that the wheel bolts to. My question is if an adapter has the same lug pattern for both the mounting holes and the lug studs is it classified as an adapter or a fancy spacer ?
Agreed with Maximum Motorsports statements regarding proper torqueing.
