I couldn't work out how the returned device object was private, so removed this part, but please correct if this is wrong.

`CPU_DEVICE` object, and `device` keywords to creation functions only
accept either this object or `None`. A future version of array-api-strict
[may add support for a CuPy
in array-api-strict is superficial only.
array-api-strict supports three 'devices'; the default `CPU_DEVICE`,
`Device("device1")` and `Device("device2")`. This allows testing of arrays on
different devices, without the need for special hardware.
`x.device` is always a `Device` object, and `device` keywords to creation
functions only accept the above three device objects or `None`. A future version of
array-api-strict [may add support for a CuPy
backend](https://github.com/data-apis/array-api-strict/issues/5) so that
more significant device support can be tested.
