Various methods and systems are provided for a system for a rotary machine, such as a compressor or turbocharger. In one example, the rotary machine includes a volute assembly and a bearing housing. The volute assembly has a first connector that is configured to interlock with a second connector of the bearing housing. The first and second connectors are configured to engage to a greater extent through relative rotation between the volute assembly and the bearing housing.
