I agree inadequate torque is usually not the issue, and on the other hand, unless the tech goes crazy with a t-handled allen wrench it's harder to over torque to the point of stretching the newer stainless steel retaining bolt.
Where it gets interesting is when a tech uses a torque wrench and torques it to 70 ft pounds rather than 70 inch pounds, not understanding the difference. That causes issues and when/if you finally get it loose, you'll have a stretched retaining bolt as well as damaged threads in the swivel turret.
Similarly, feel is important in the initial tightening to ensure all the parts are properly aligned, oriented and seated, so a smaller allen wrench or T-handle wrench is preferable when snugging it up prior to torquing it. If the tech just starts with the torque wrench, they lose some feel and may not notice a trapped washer, pinched o-ring, etc.
In that regard, I'd almost prefer a bad tech just stick with moderate pressure on a T-handled allen wrench as they can do less damage with that then they can with the longer moment are of a torque wrench.
I suspect the original problem was caused by a) the retainer not being tightened enough, b) the retainer being over tightened and stretched in the past, c) the washer being missing, allowing excessive end play and cocking that allowed the o-ring to extrude or d) maybe (less likely) the plastic washer getting trapped in the connection and causing it to be come loose when it worked free.
