"... We'll cite two kinds of rotation ciphering machines: the Jefferson
disk and the ..."

And the term "rotation" crops up in the actual ciphering technique, e.g. 
http://en.wikipedia.org/wiki/Caesar_cipher

"... For instance, here is a Caesar cipher using a left rotation of
three places, equivalent to a right shift of 23 (the shift parameter is
used as the key): ..."

And as the technology "evolved" the terminology did not and got infused
into modern technology.

E.g. "Hey Barman, can you put that on the slate mate." :)

I'm not sure if my reasoning is accurate or not, but it sounds darned
good to me. :)
