I had a similar problem with mine. I made my own adapter and found that the 
first time I tried to remove the filter the entire adapter spun because the 
spin-on filter gasket stuck to the adapter the same as it does on a "normal" 
car. When the adapter spun, so did the adapter bolt. I solved mine by 
drilling and tapping a hole on the inside of the adapter facing the filter 
head and putting a short bolt there that would butt up against a depression 
inside the filter head thus preventing it from turning. I didn't tap the 
hole all the way so the bolt would go in part way and then attempt to cut 
its own threads as I tightened it and thus be self locking, I hope. So far 
it has been that way about 3 years.
