With the aura attack, I mainly say the attack  was a factor as the intention was to kill the grimm. With the machine the purpose would be to transfer aura as safely as possibly so it being a forcible attack wouldn't come into play.

The bug did demonstrate that certain grimm could directly interact with aura. How it removed the maiden power is questionable but it would had have to manipulate and influence aura to do so.
