class MongoCommandCursor extends AbstractCursor implements MongoCursorInterface

PSR1 recommends that each class must be in a namespace of at least one level to avoid collisions.

The parameter $connection is not used and could be removed.

The parameter $hash is not used and could be removed.

The parameter $document is not used and could be removed.

            $this->cursor = $this->db->command($convertedCommand, $this->getOptions());

It seems like $this->db->command($convertedCommand, $this->getOptions()) of type integer is incompatible with the declared type object<MongoDB\Driver\Cursor> of property $cursor.

        }

        return $this->cursor;

The expression $this->cursor; of type integer|MongoDB\Driver\Cursor adds the type integer to the return on line 66 which is incompatible with the return type declared by the abstract method Alcaeus\MongoDbAdapter\AbstractCursor::ensureCursor of type MongoDB\Driver\Cursor.
