More details would be nice, don't want to pry, but was that an in house course run by the company you work for? if you are unsure of any aspects of your role then I would have expected some sort of employee advice centre you could call on, to be honest with you I do find it odd, regarding the sort of work you are employed to do, and yet not much information or engineering equipment provided, please don't think I'm being dismissive of your role, just seems an odd question seeing as you have had training etc, anyway ask for information on torque setting and tooling for the equipment you are installing, good luck.
