Aw c'mon now the shaking is half the fun, besides the bees don't care.
An a more serious note, do note attach the queen cage with the strap as shown. Either just turn her loose after dumping the bees in, or if you must hang the cage, hang it by a piece of floss or monofilament fishing line. This lets the cage spin freely and helps stop the bees using the queen cage as a starting point for all kinds of crazy comb.
