I made the experience that Torque does not handle tables without a 
primary key very well because most operations are based on the pk. 
Deleting from one of those tables won't work as well, you'll get some 

Since I didn't have the time to examine this behaviour any further, I 
now add a primary key to every table, even if it doesn't need one, just 
to keep Torque working.

It's a conceptual problem.
