Is there not like a bunch of electronic components that would get twisted and ruined of they just kept spinning? Or is there a limit to how many rotations they can do before needing to counterspin?

You have a Slip ring at the bottom axis of rotation that can transmit electricity even if you rotate it around freely.
The way to think about it is a common 3.5mm headphone connector. It can rotate freely around one axis and still work because the contact surface is round and the connector push against it to make contact.
You can do the same thing on a larger scale and it can include a hydraulic connection.
Google “Slip ring” and like at image hits and you find lots of examples
