Well, of course you have no choice but to grab a bird by its body if it doesn't step up but aviary birds (I have canaries and finches and keep my tiels and budgies as aviary birds, too) hardly ever need to be grabbed so doing it once a year to check on the level of breeding condition and clip nails preparing for breeding (passerines) is not going to arouse the bird. Parrots are companion birds and imprinted on people (usually) so the situation is different, especially if this is something done every day.
As to needing to touch or grab the bird in order to put on a harness, I guess it all depends on how well you train it because, as far as I can tell, the human doesn't need to touch the back of the bird. You put the harness over the bird's head, open one wing and slip it on, open the other wing, slip it on, buckle it. Voila! Bird on a harness and the back was not touched.
