I have a setup with 4 cylinders placed next to each other in following configuration. The cylinders are made of .2mm stainless steel. I would ideally want to rotate them along their axis using a single actuator/motor. What would be the best mechanism to do so?

I'd like to keep the cylinders as close to each other, due to space constraints. Any references would also help.
