If you mean "Twirly" pass, then yes. Other sorts, no.

But I think the nickname is misapplied for the bus isn't it - I have an
idea that on London buses they are valid at all times, not just after
09:30?

The validity of the passes, in London, has changed. When introduced they
could not be used "too early", hence the name was coined.
