Bug: When trying to create sturdy devices from one of it's children, it creates a stone cutter instead

[EngineerSmith]

When trying to add my own blocks to the sturdy devices I found that it first created stone cutter tables with them instead? At first I thought I was doing something wrong but I've noticed it happening with others too. So I assume it isn't my doing as I'm not altering the code that managers the devices except to add to the array of device children under Sturdy devices.
