Description:
 def create(self, name, redirect_uri=None):
 """Create a new Device object. Devices tie Users and Applications together. For your Application to access and act on behalf of a User, the User must authorize a Device created by your Application. This function will return a `device_token` which you must store and use after the Device is approved in `client.authenticate_device(api_token, device_token)` The second value returned is an `mfa_uri` which is the location the User must visit to approve the new device. After this function completes, you should launch a new browser tab or webview with this value as the location. After the User approves the Device, they will be redirected to the redirect_uri you specify in this call. Args: name (str):
 Human-readable name for the device (e.g. "Suzanne's iPhone") redirect_uri (str, optional):
 A URI to which to redirect the User after they approve the new Device. Returns: A tuple of (device_token, mfa_uri) """
